HVMOP_set_mem_type allows invalid P2M entries to be created

ISSUE DESCRIPTION The implementation in Xen of the HVMOPsetmemtype HVM control operations attempts to exclude transitioning a page from an inappropriate memory type. However, only an inadequate subset of memory types is excluded. There are certain other types that don't correspond to a particular...

CVE-2013-1918

CVE-2013-1918 affects Xen hypervisor (4.1.x, 4.2.x and earlier). The vulnerability arises from certain page table manipulation operations that are not preemptible, allowing a local privileged VM (PV kernel) to cause a denial of service via vectors related to deep page table traversal. Impact is d...

Several long latency operations are not preemptible

ISSUE DESCRIPTION Page table manipulation operations for PV guests can take significant amounts of time, as they require all present branches to have their type and thus contents verified. While the most frequently used operations had been made preemptible in the past, some code paths involving...
